This course is intended for learners who have several years of experience with air quality planning and have general knowledge about area designations, but have not yet applied their knowledge to analyze the technical factors that are typically used as part of the area designations process. After completion of this course, learners will be able to apply the technical factors as part of the area designations process.

This course is comprised of two modules:

1. Overview of the Process and Timeline for Area Designations
It is recommended, but not required, that learners complete the course BASC110-SI: Introduction to the National Ambient Air Quality Standards (NAAQS) and the module “What are Area Designations?” before taking this module.
After completion of this module, learners will be able to explain the process and timeline for designating areas under the Clean Air Act. Specifically, learners will be able to:

• Identify some of the Clean Air Act (CAA) requirements for the area designations process.
• Explain tribal participation in the area designations process.
• Explain the public's role in the area designations process.
• Explain each of the milestones for the area designations process.

2. Area Designations Factor Analysis
After completion of this module, learners will be able to apply the area designations factor analysis to identify potential boundaries for a nonattainment area. This module is structured into five factor-specific lessons. Each lesson provides context for each factor to prepare the learner to then apply a scenario at the end of the lesson. The module concludes with a “weight-of-evidence” lesson, where the learner synthesizes the information that has been applied through each factor-specific lesson. Lastly, this module includes a “real world examples” section and a “helpful resources” section, both of which include links to further information. Learning objectives for this module are as follows:
Introduction Lesson
• Describe the purpose of the area designations factor analysis.
• Identify the historical five factors used for the area designations factor analysis.
Air Quality Data Factor Lesson
• Explain how assessment of monitoring data is used in the air quality data factor analysis.
• Explain how exceptional events can affect the air quality data factor analysis.
• Apply the air quality data factor, given an example scenario.
Emissions and emissions-related data factor lesson:
• Explain how the emissions and emissions-related data factor analysis helps aid with defining the nonattainment area boundaries.
• Define the emissions and emissions-related data factor analysis.
• Describe the three main categories of data used for the emissions and emissions-related data factor analysis.
• Apply the emissions and emissions-related data factor, given an example scenario.
Meteorology factor lesson:
• Explain why meteorology data are used for area designations.
• Describe the tools used for evaluating meteorology data.
• Apply the meteorology factor, given an example scenario.
Geography/topography factor lesson:
• Explain why geography/topography data are used for area designations.
• Apply the geography/topography factor, given an example scenario.
Jurisdictional boundaries factor lesson:
• Explain what the jurisdictional boundaries factor is used for.
• List examples of jurisdictional boundaries.
• Explain consideration of tribal jurisdiction.
• Apply the jurisdictional boundaries factor, given an example scenario.
Weight-of-evidence lesson:
• Apply weight-of-evidence to decide upon a recommended nonattainment area boundary.
